Geology-oriented
research institutes and higher education establishments of Moscow
and Leningrad
helped greatly in teaching and training of Armenian scientists.

In the
past years, there were carried out fundamental investigations in various fields
of geology and geography, which resulted in several dozens of monographs and
numerous scientific publications.

Main results

Biostratigraphy.The schemes of stratigraphic dissection of
the Phanerozoic deposits of Armenia
(D-Q), including the scheme of geological staging and zonation classification
of the Jurassic, Cretaceous and Palaeogene deposits were developed. The
continuous section between the Eocene and Oligocene is accepted as a
stratigraphic type within the Mediterranean belt.

USSR.

In the field of the theoretical geodynamics
and tectonics, Academician A. T. Aslanian has developed a hypothesis on free
nutational oscillations of the poles, the origin of the Earth's magnetic field,
and a quantified model of the substance composition and internal structure of
the Earth, and obtained quantitatively justified evidences on the Earth's
radius decrease.

The seismic hazard assessment (seismic
zonation, and long-term earthquake forecast) in the Armenian Highland was made,
a geodynamic model of newest stage was proposed, and the active tectonics map
was drafted.

The outcrops of the crystalline basement of
the Baikalian and Hercinian consolidation age were revealed, their initial
compositions of metamorphic facies and the geodynamic conditions of their
formation were determined.

"The Map of Magmatic and Metamorphic
Formations of the Armenian SSR" and "The Map of Crystalline Basement
of Armenia" were drafted.

Structural-and-geodynamic conditions of
area volcanism manifestations were revealed, and regularities and genetic
peculiarities of ignimbrite volcanism were found out "The Maps of Mesozoic
and Cenozoic volcanic formations" were drafted.

Ore Formation and Metallogeny. Academician
I. G. Magakian contributed greatly into the development of the ore formation
theory and the metallogeny.

Geological-and-structural conditions for
localization, formation and location regularities of the commercial deposits of
Armenia were found,
regularities in distribution of rare and noble elements in the major ore
formations of Armenia
were revealed.

A new type of gold-ore mineralization
localization was distinguished.

There were compiled "The World
Metallogenic Map", various-scale metallogenic and forecasting-metallogenic
maps of Lesser Caucasus and Armenia,
large-scale geological and geological-structural, and forecasting-metallogenic
maps of the main ore fields and deposits of Armenia.

Armenia's magmatic, volcanic, metamorphic
and ore formations based on the isotope (K-Ar, Rb-Sr) dating. For the first
time, there was proved participation of sea water in forming of copper-molybdenum
deposits.

Armenia were revealed and classified, and
"The Map of Mineral Waters of Armenia" was compiled. Lesser Caucasian
province of carbonate boron-bearing rare alkaline-metal waters was
distinguished, and the soil-hydrochemical method of prospecting for mineral
resource deposits was developed.

The engineering-geological technique for
classification of mountainous areas was developed, various-scale
engineering-geological maps and engineering-geological zonation maps for
individual regions and towns of Armenia
were drafted.

of Sciences of the Republic of Armenia

A number of
analytical laboratories such as chemical, spectral, hydrochemical and isotopic
is functioning in the Institute of Geological Sciences of the National Academy of
Sciences of the Republic
of Armenia. These
laboratories provide comprehensive and diversified study of substance compositions
of rocks, ores, minerals, fresh and mineral waters:
